ports too small?
 
4 Attachment(s)
this was made by a forum member and I bought it from the guy he sold it to. the manifold is solid, but worried the ports are too small for the 60 trim I will be running. opinions please!! small excedrin bottle used for reference

It will work, the turbine inlet is a bit small though, might want to make a that bigger with a piece of box tubing the size of the turbo inlet. Or w/e you want to replace that little tube with. The head side ports are normal.

Is this Loki's old manifold?

Pretty sure it is.

Ok?? Anything to actually help?

ok ok if you could replace the turbine inlet with something larger (you can reuse the flange, just cut it to match the turbo inlet) then it'd probably be fine.

thank you very much!! too bad my welding buddy just left for the Air Force last month.

how much power restriction do you guys think this could cause if I leave it as it is?

3.73e+28 yoctowatt, give or take...

Seriously, that's pretty much an impossible question to answer, other than to say it will be sub-optimal.

too small for my opinion if you care. better bigger than smaller.

That's what she said, lol

Seriously Zoom, can't you just make the hole bigger? do you own a cutoff tool and air compressor, or maybe even a dremmel, even though it would take like three days.
